评价现代热带轧机的经济效益,通常考虑三方面因素:轧制带钢的尺寸精度、冶金质量和能耗及生产率。所有这些因素与加热控制有很大关系。尺寸和冶金性能与板坯出炉温度的精度和均匀度有直接关系;加热炉的燃料消耗约占热带钢工艺过程总能耗的一半,由加热和轧制过程产生氧化铁皮所造成的金属损耗 To evaluate the economic benefits of modern tropical rolling mills, three factors are generally considered: the dimensional accuracy of rolled strip, metallurgical quality and energy consumption, and productivity. All of these factors have a lot to do with heating control. The size and metallurgical properties are directly related to the accuracy and uniformity of the slab tapping temperature. The fuel consumption of the reheating furnace accounts for about half of the total energy consumption of the strip and is caused by the metal loss caused by the scale during heating and rolling
